It burns GoodWhite leftoids that they have to expend so much cognitive capital hewing to codewords and poopytalk to vent their spleens against the ravages of Diversity. It kills them inside that they have to speak in Fake Rhetoric to, in effect, hide their rank hypocrisy not only from BadWhites but from themselves.
For example: Blacks murder each other at stunningly high rates in the US -- 115 on average every week. The horrific statistic of these "youths" is simply not mentioned by liberals. The real hot "Amerikkka is racist" issue is the 5 blacks per week who are killed by police officers.
